It may be a tough watch, but, boasting a quartet of excellent performances, Fran Kranz's directorial debut is a technically adept, emotionally exhausting yet deeply cathartic film that couldn't be more timely.

While stories such as We Need To Talk about Kevin capitalised on the shock value of its horrifying events by playing with a non-linear narrative, Kranz's film doesn't feel the need for any extra artifice.

Movies trade in closure. Mass is honest enough to admit it is not always there to be had.

Mass is a film of harsh truths, visceral emotions, and anguished action: one that manages to unearth redemption and forgiveness from the void of tragedy and hate.
